FOLDING BOX.

Application led July 14,

To all whom t may cm1/1era.'

Be it known that I, EDWARD E, PINKER ToN, a citizen of theUnited/States, and a resident of the city of `Chicago, county of Cook,and State of Illinois, have invented certain new and useful Improvementsin Folding Boxes, of which the following is a speciication.

My invention relates to improvements in folding boxes and has for itsobject the provision of a simple construct-ion of this character wherebya strong, simple and efficient folding box may be provided.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a plan View of the blank from which the box is made.

Fig. 2 is a perspective view of the same partially folded into box form.

Fig. 3 is a longitudinal section of the completed box, said sectionbeing taken substantially on the plane of the box indicated by the line3-3 in Fig. 2.

Fig. 4 is a section taken on line 4--4 of Fig. 3, and v Fig. 5 is alongitudinal section of the box similar to Fig. 3 but showing the boxarranged in` slightly different form.

The box has been illustrated in the drawings as resting upon a certainside thereof, and for convenience in description and for the sake ofclearness, this side of the box is termed the bottom thereof, but it isto be understood that this term and the other terms employed indescribing the box are purely reln ative and describe the box only whenresting on said side as the bottom. Obviously the box may be turned torest on any of its six sides, in which position the lowermost side wouldconstitute the bottom of the box, under which circumstances thefollowing description would not apply. However, it is a simple matter toarrange the box with the side thereof selected as the bottom inlowermost position, whereupon the following description applies. ln theform of construction as illustrated in the drawings the box is made of asingle blank of suitable paper stock material comprising a bottom 6having end walls 7 and 8 at its opposite'edges and side walls 1921.Serial No.4 484,608.

9 at the remaining edges. rlhe side walls 9 are provided with end flaps10 to be ar ranged across the corresponding end of the box as shown.Each offthe side walls 9 is also provided with two inwardly extendingflaps 11 and 12 separated from each other at a substantially centralposition of the box, the Haps 11 being'somewhat longer than the flaps 12and arranged adjacent the end wall 7. The end wall 7 carries a flap 13of a length to cover the Haps 11 in the box, and flap 13 is providedwith an extension 14 of a length equalto the height of the box.Extension 14 is provided with a. further extension 15 adapted to bearranged within the box as shown, and extension 14 is also provided witha number of circular perforations 16 for a purpose to be mentionedhereafter. The end wall 8 is provided with, a cover flap 17 adapted tocompletely cover the box and an extension 18 extending across the end 7thereof and a locking tongue 19 adapted and arranged to be inserted in aslit 2() provided at the juncture between end wall 7 and bottom 6 asshown.

In making up the box the side walls 9 are bent upwardly and flaps 10,11and 12 bent inwardly as indicated in Fig. 2. Then end wall 7 isbentupwardly and flap 13 extended over the flaps 11, the extensions 14 and15 being bent into the body of the box In the form illustrated in Figs.3 and 4 the extension 14 is arranged as a central vertical partition, inwhich position the openings 16 serve as receiving openings for arlticles such as h'airpins, crayons, or-the like. In the form illustratedin Fig. 5 both exten sions 14 and 15 are folded flat against the undersides of the flaps 11, whereupon the interior of the box is open andunobstructed and adapted to receive larger articles such as a package ofhairpins, a pocket book, or

other similar and larger articles. In closing the box, end wall 8 isbent upwardly and cover flap 17 brought over the box, exten-v sion 18extending across the end 7 thereof and tongue 19 being inserted in slit20 as shown. By this arrangement a comparatively strong and highlyeflicient box is formed from a single blank of material.

l/Vhile I have illustrated and described thel preferred form ofconstruction for carrying my invention into effect, this is capable o'variation and modification without departing from the spirit of theinvention. l. therefore, do not wish to be limited tothe precisedetailsof the construction set forth, but desire to avail myself of suchvariations and modifications ascome within the scope of the appendedclaims.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

1. A folding box comprising a bottom having side Walls at opposite edgesthereof; flaps on said side wall extending inwardly therefrom, adjacento-ne end of said box; an end wall adjacent said side wall flaps; and aflap on said adjacent end wall overlying said side wall flaps and havingan extension folded aro-und said side Wall iiaps and inserted within thebox, said inserted portion forming a partition in the box, substantiallyas described.

2. A folding bOX Comprising a bottom having side walls at opposite edgesthereof; flaps on said side walls extending inwardly therefrom; an endwall at one end of said bottom; a flap' on said end wall overlying saidside wall flaps and having an extension folded around said side wallfiaps and inserted within the box; a second end wall at the other end ofsaid bottom; a cover flap onl said second end wall extending the fulllength of said box and covering the other end wall flap; and a lockingtongue at the free edge of said cover iap, there being a slit in the endof the box to receive said tongue, substantially as described.

8. A folding box comprising a bottom having side walls at opposite edgesthereof; flaps on said side walls extending inwardly therefrom, saidflaps being located adjacent one end and extending substantially onehalf of the length of the box; an end wall at one end of said bottomadjacent said side wall flaps; and a Hap on said end wall overlying saidside wall Haps and having an extension folded around said side wallflaps and inserted within the box, said inserted portion forming acentral vertical partition in the box, substantially las described.

4. A folding box comprising a bottom having side Walls at opposite edgesthereof; flaps on said side walls extending inwardly therefrom,saidllaps being located adjacent said endfwall and extendingsubstantially one half of the length of the box; an end wall at one endof said bottom adjacent said side wall flaps; a flap on said end ivall foverlying said side wall flaps and having an extension folded aroundsaid side wall flaps and inserted within the box, said inserted portionforming a central vertical partition in the box; a second end wall atthe other end of said bottom; a cover Hap on said second end wall; and alocking tongue at the free edge of said cover flap, there being a` slitin the box to receive said tongue, substantially as described.

5. A folding box comprising a\ bottom having side walls at oppositeedges thereof; iaps on said side walls extending inwardly therefrom,there being two flaps on each side wall separated from each otherat'substantially' the center of the wall; an end wall at one end of saidbottom; a flap on said end wall overlying the adjacent pair of said sidewall flaps and having an extension folded around said pair of side wallflaps and inserted within the box, said inserted portion forming acentral vertical partition in the box and being perforated; a Second endwall at the other end of said bottom; a cover flap on said second endwall extending across the top of said box; an extension on said coverflap extending across the corresponding end of said box; and a lockingtongue at the free edge of said' cover flap extension. there being aslit in thc box to receive said tongue, substantially as described.

ln testimony whereof l have signed my name to this specification in thepresence, of two subscribing witnesses.
